const_cast operator
| const_cast operator | Cast to modify qualifiers |
postfix-expr := const_cast < type-id > ( expression ) |
The const_cast operator performs a type cast that can add or remove const and volatile qualifiers. No other modifications to the type are permitted.
If you cast away a const or volatile qualifier from an object, and then modify the object, the behavior is undefined.
Example
template<typename T>
T& unsafe(const T& x)
{
return const_cast<T&>(x);
}
